My invention relates to a reel for coiling wire such as is used fortaking up the wire which is discharged by the last stand of a rollingmill Reels of this type are operated either on the Gar- 5 rett or on theEdenborn system. In the former, the nozzle which delivers the wire tothe reel is stationary and the basket in which the wire is deposited inturns is rotated, whereas in the latter the nozzle is rotated and thebasket is stationary. Each system has its particular merits and istherefore preferred to the other according to the conditions in which itis to be used in practice.

With a reel according to the Garrett system wire of any cross-sectioncan be wound up, whereas a reel according to the Edenborn system canonly be used with wire of round cross-section. On the other hand, with areel according to the Edenborn system the wire is positively guided whendeposited inturns in the basket so that the turns are not liable to jumpout of the basket even when the latter is rotatedathigh speed.Furthermore with a reel according to the Edenbornsystem, the revolvingmasses are not so big 5 as with a reel according to the Garrett system.

It is an object of my invention to provide-a reel for coiling wire whichcan be selectively operated either on the Garrett or on the Edenbornsystem. This I accomplish by removably mounting the rotating parts ofeach system,--i. e. the basket with the Garrett system and the nozzlewith the Edenborn system-on the driving shaft of the reel so that eachof them can be easily replaced by the other at will. In this way, I canrotate either 5 the basket or the nozzle and thus operate the reeleither on the Garrett or on the Edenborn system.

It is a further object of my invention to provide a reel-of the type setforth in which the turns of the coil are formed within the same space ofthe reel both with the Garrett and the Edenborn system. This Iaccomplish by so arranging the nozzle used with the Garrett system thatits outlet end lies in the plane which is described in space by theoutlet end of the nozzle used with the Edenborn system, and by furtherarranging the basket used with the Garrett system in the coiling spaceof the Edenborn system. With this arrangement the other members of thereel, i. e. the means for tilting the basket and for feeding water tothe basket for hardening purposes can be used without variation withboth systems.

It is a. further object of my invention to provide a reel of the typeset forth in which the parts which have to be replaced when the reel istransformed from the Garrett system to the March 3, 1934 Edenborn systemarid vice versa are easily accessible. For this purpose I provide eachof these parts with a coupling head by which the respective part ismounted on the top end of the driving shaft of the reel which projectsabove the coiling space.

It is a further object of my invention to provide a reel of the type setforth in which the electric driving motor is mounted directly on thedriving shaft without requiring additional space. This I accomplish byarranging the motor within the coiling space so that it is surrounded bythe latter.

In this case I prefer to provide a cooling jacket around the motor inorder to protect the moto against the heat of the coil.

With these and other objects in View, I will now describe my inventionmore fully in detail, reference being had to the accompanying drawing inwhich Fig. 1 is a vertical section of a reel, according to my invention,which is adapted for the Garrett system, and

Fig. 2 a vertical section of the same reel adaptspace i and is thereprovided with a key 5 and.

fastening screws 6 for a purpose "which will presently appear.

In case I wish to operate my reel on the Gar rett system, I make use ofa coupling head i i (Fig. -1) carrying the basket 8. The coupling head Iis mountedon the shaft ll by means of the key 5 and the screws 6 in amanner which will appear from Fig. 1 so that the basket 8 will dependdownwardly. I complete the arrangement by mounting a stationary nozzle9' on the cover ill of the reel.

In case I wish to operate my reel on the Edenborn system, Imake use of acoupling head I" (Fig. 2) carrying a nozzle 9". The coupling head I"ismounted on the shaft t by means .of the key 5 and the screws 6. Sincein the Edenborn' system the means which take up the coil are not rotatedI need not provide a separate basket in this instance; The nozzle 9 isso shaped that its outlet end lies on the same level as the outlet endof the nozzle 9' in Fig. 1 and at. the same distance from the axis ofthe reel.

It vwill be readily apparent that I have thus provided a reel forcoiling wire which can. be

easily transformed at will into one of the Garrett or one of theEdenborn type. It is only necessary for this purpose to exchange the twocoupling heads 1 and 'l" and the parts associated with them.

The coupling head 'I is also fitted with stop pins ll having notchedends. I provide these pins in order to prevent the uppermost turns fromrising from the coil. The pins 1 I and the nozzle 9" are slidablymounted so that when the reel is tilted they can be moved out of the waythus to clear the path for the discharge of the finished coil from thecoiling space. The cover I0 is controlled by known means so that it willopen only when the reel has reached almost its downward position. Asthese means are known I need not describe them here.'

Tilting of the reel is accomplished by means of trunnions I2 which arearrangedabout midway the height of the coiling space I so that the reelwill be normally kept in balance. One of said trunnions is provided witha. longitudinal bore l2 (Fig. 1) through which water for hardening andcooling purposes may be fed to the reel. The cooling water is fed to thecooling jacket 3 by means of a tube I 3.

It will be further noticed that the basket 8 shown in Fig. 1 is providedwith bores M for the hardening water as more fully described in myPatent 1,977,989. I5 is a ring disposed below the basket 8 whichprevents the water coming in through the bore l2 from passing around thebasket 8 so that the whole water is guided to the bores l4. 7
